TRUSS.

Specification of Letters Patent.

Patented Aug. 6, 1907.

Application filed October 19, 1906. Serial No. 340,112.

To all whom it may concern:

Be it known that I, EMERY H. PARKER, of Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Trusses; and I hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, which form part of this specification.

This invention is an improvement in trusses, and its object is toprovide for detachably attaching the leather parts to the textile coversof trusses in such a manner that they can be readily removed from thecovers without ripping or damaging the cover or parts, and the coverscan also be readily removed from the metal parts without any ripping.This construction allows the truss covers to be removed and cleansed orwashed without injuring the metal or leather parts by water or acids,and the same leather parts can be readily reattached to the covers thusenabling the covers and leather parts to be used and re-usedindefinitely.

Another object of this invention is to enable the de tachable back-padshield of deer-skin or other material, and leather parts on a doubletruss to be readily attached or detached without ripping or injury tothe covers, the leather parts, the back pad, or any portion of thetruss.

The invention will be fully understood from the following explanation inconnection with the drawings, which show a truss provided with removablecovers and detachable leather parts and back-pad-shield, in accordancewith the invention.

In the drawings-Figure 1 is a perspective view of a double trussprovided with my improved detachable covers, leather parts and back padshield. Fig. 2 is an enlarged horizontal section through the back padand covers. Fig. 3 is a perspective view of a single truss member withthe cover partially removed and one of the leather parts detachedtherefrom. Fig. 4 is a detail sectional view showing another mode ofattaching the leather parts to the cover.

The truss, so far as the metal and main back pad portion thereof areconcerned, may be of any suitable construction, either single or double.

I have shown in Fig. 1, a double truss composed of oppositespring-members l, to the forward ends of which truss pads 5 areattached, and these springmembers are fastened at their rear ends to theback pad 2, of any suitable construction, by means of loops 2 and ascrew 1, passing through coincident perforations 1' in thespring-members, as usual.-

The spring-members 1 are provided with covers 1 of fabric, or othermaterial which can be washed or cleansed, and these covers are slippedendwise onto the spring-members. I

The covers are detachably attached to the springmembers by means ofleather parts 1 connected to the front ends of the covers and providedwith eyes adapted to engage pins 4 attached to the forward ends of thespring-members. The rear ends of the covers are held in place betweenthe springs and the back cover 2.

The leather parts 1 are detachably attached to the covers, as by meansof glove-fasteners. One member 1 of the glove fastener can be attachedto the cover and the other member I can be attached to the leather partas indicated in Fig. 3. This enables the leather part to be readilyremoved from the cover, either before or after the cover is removed fromthe springmember.

Instead of fastening the leather parts 1 to the exterior of the coversas in Fig. 1, they might, if desired, be telescoped into the end of thecover and fastened internally thereto by means of detachable fasteners,as indicated at 6 in Fig. 4.

The strap or binding leather 6, shown in Fig. 1, and ordinarily employedin double trusses, may be detachably attached to the pins 4 on thespring-members, as indicated in Fig. 1, of the drawings. These pins 4are also ordinarily used to fasten the truss plates 4 to thespring-members.

The baclepad-shield 3 is detachably attached to the back pad 2 by meansof suitable fasteners which may be glove fasteners, one member 2 ofwhich is attached to each end of the back-pad-shield and is adapted toengage the other members 2 attached to flexible extensions 2 on the backpad.

By means of the construction described, it will be obvious that thecovers 1 can be readily attached to or detached from the spring-members;that the leather parts 1 and 6, can be readily attached to or detachedfrom the covers and spring-members and that the cover can be cleansed orwashed while detached, and all the parts can be easily replaced on thespring-members. The back-pad-shield 3 can be similarly readily removedfrom or replaced on the back pad 2.

I have shown glove fastener connections but I do not confine myselfthereto, as other suitable readily detachable devices may be used toconnect the leather parts to the cover.

Having fully described the nature and objects of my invention, what Iclaim as new and desire to secure by Letters Patent is:

1. In combination with a truss spring-member, a removable covertherefor, and truss leather parts dctachably attached to said cover andadapted to engage a retainer 0n the springmember to fasten the cover inposition.

2. In combination with the back pad of a truss having flexibleextensions at its ends, of a skin-back-pad shield dctachably attached tosaid extensions.

The combination with a double truss, spring-members detachably attachedto the back pad of the truss, removable covers slipped on saidspring-members and leather fastening devices detachably attached to saidcovers and engaging retaining; devices on the spring-members.

4. In combination with a spring-member of a truss, a removable textilecover therefor adapted to be slipped end- Wise thereon, a trussleather-part adapted to be detachably attached to said cover and to thespring-member to retain the covering in position on said member, andglove fastener devices detachably connecting the leather-part to thecover.

5. The combination of a truss having a back pad, a skinback-padcover andmeans for detachably attaching the said cover to the back pad, oppositespring-members attached to the back pad, truss pads on the forward endsof said members, removable textile covers adapted to be slipped on saidmembers, leather parts detachably attached on the forward ends of saidcovers and detachably engaging retaining devices on the said members,and a fastoning strap detachably connected to the spring-members andcovers, substantially as described.

cover therefor adapted to be slid thereon, and leather parts detachablyconnected to said cover, and removable there from when the cover is tobe washed.

7. The combination of a truss having a back pad, opposite spring-membersattached to the back pad, pads on the forward ends of said members,removable textile covers adapted to be slipped on said members, leatherparts detachably attached to the forward ends of said covers anddetachably engaging retaining devices on the said members, and a leatherfastening strap detachably attached to one endof aspring-member,substantially as described.

In testimony that I claim the foregoing as my own, I afiix my signaturein presence of two witnesses.
